A woman described by authorities in Mexico as the leader of a Sinaloa Cartel cell responsible for fueling a wave of violence in the resort city of Cancun was captured on Thursday in the state of Puebla.

Mexican Law enforcement officials announced on Friday the arrest of 48-year-old Leticia Rodríguez Lara, aka “Doña Lety” or “La 40,” an alleged leader of the Sinaloa Cartel based in the state of Quintana Roo.

Mexican Marines and the Deputy Prosecutor for Specialized Investigation of Organized Crime (SEIDO) arrested Leticia Rodríguez Lara at a hotel near Puebla City on Thursday.

Authorities say “Doña Lety,” a former federal police officer, formed a criminal network tied to the Sinaloa Cartel which included former corrupt members of the police force, which she recruited through acquaintances inside the department.

Lara is believed to have controlled the trafficking and distribution of narcotics along with extortion of bars and restaurants in the resort cities of Cancun and Playa del Carmen.

Moreover, officials say she is responsible for carrying out several attacks against rival organized crime groups in Cancun and business leaders who failed to pay extortion payments.

According to the Yucatan Times, Rodríguez Lara’s growing network quickly became one of the most violent cells linked to the Sinaloa cartel, where deserters of rival criminal groups including Los Zetas and Gulf Cartel were recruited into its ranks.

Authorities have linked Rodriguez Lara to January’s attack on the Quintana Roo State Prosecutor’s Office in Cancun, which occurred one day after a shootout erupted at the Blue-Parrot Bar in Playa del Carmen, which resulted in the deaths of five people including an 18-year-old U.S. citizen and 15 others wounded.
